Hi, I changed my old ATI for new NVIDIA graphics card (660 ti) and I am having issues with unstable X. I am using newest nvidia-drivers (310.19) and newest Xorg-server (1.13.1). everything boots ok but after some time X freezes (sound works) and I have to do hardware reboot (control+F# doesnt work), the /var/lof/Xorg.0.log.old: http://pastebin.com/9wW4QDRv.
I am using 3.7.1-pf sources and my .config:http://pastebin.com/Rjimvc0n
I tried intel_iommu=igfx_off and iommu=soft in kernell boot line.
It seems to occur faster if I use flash player and after few minutes of using wine (World of Warcraft, Diablo III)
Thank you for replies.
